Introduction
Tek-Trol’s Explosion-Proof Temperature Transmitter is a micro-processor based temperature transmitter, that
has temperature sensors such as Thermocouple(T/C), Resistance Temperature Detctor (RTD), milliVolt (mV),
and Resistance. Tek-Temp 2100A Model is explosion-proof type and has high precision, better reliabilty, and
uses a remote communication system. This transmitter is enabled in HART communication with Host, HHT
(HART Hand-Held Terminal), or PC Configurator. The transmitter has various variables in host that is enabled
to be changed, configured, and calibrated by users with the help of HHT.
Measuring Principle
Benefits
A temperature transmitter is typically connected to a 24 VDC power source. The temperature sensor such
as RTD or Thermocouple measures the temperature of the medium. The output signal of the sensor is first
modified into a standard format with the help of a Signal Conditioning processes such as Amplification,
Isolation, Filtering, Linearization, and Excitation by the transmitter. The transmitter amplifies and converts the
output to a high-level analog signal, usually a standard 4-20 mA signal. It then transmits the amplified signal
to the control device by means of long cable runs.
• High Accuracy: ±0.1% FS (at 68 °F (20 °C), mV input)
• Long-Term Stability
• Selection of various T/C, RTD, mV, Ohm
• Data Configuration with HART® configurator
• Also available with fieldbus
• Continuous Self Diagnostic Function (sensor, memory, communication)
• Automatic Compensation: Linearization of sensor input, ambient temperature compensation
• Fail-mode process function by hardware and software
• EEPROM Write Protection
• I/O Isolation: Grounded T/C input
• CE EMC Conformity Standards (EN50081-2, EN50082-2)
